Abstract
Disassembly economic order quantity models are proposed in this paper in order to reduce inventory costs in reverse logistics. The problems is to determine the quantities and the timings of disassembly operations to generate components for which there are known, continuous and constant demands over a planning horizon. Disassembly operations generate unnecessary inventories when the demands are not the same for all components. The proposed models integrate disposal decisions to handle this inventory surplus. Three new models are developed to determine reorder intervals in disassembly systems according to fixed disassembly order costs and inventory costs. The first one is a single stage model (one product to disassemble with several requested components) with one reorder interval to determine. The other two are for multi-stage disassembly systems (one reorder interval to be determined for each stage) under nested policies and integer-ratio ratio policies.
